Appears to be a debug build of the Ghost in the Shell Stand Alone Complex for the PlayStation 2. Unfortunately, I'd had little luck actually playing for longer than 5 seconds upon opening a level due to what appears to be a lock-up of sorts, though this may have been due to the emulator.
As evidenced by the label on the disc, it appears to be at least two months before the final NA release and at least five months after the initial JP release.
